Does gardenia like sunlight?
The web tells everyone about whether gardenias like sunlight and the real reasons for the yellowing of gardenia leaves, green plants and flowers. Let's learn about it together next.
The beauty of gardenias is not only in their white flowers, but also in their rich aroma, which is why they are loved by so many flower friends. Gardenias are not easy to cultivate plants. They have high requirements for light, soil and other aspects. Many flower friends like them but can't keep them for a long time. Whether gardenias can be exposed to the sun, flower friends also have different views. Flower friends keep asking, does gardenia like plenty of sunlight or semi shade, and why do the leaves always turn yellow?
Gardenias like light, why do the leaves still turn yellow? Several main reasons should not be ignored!
Theoretically speaking, gardenias are heliophilous plants, but compared with very heliophilous plants like jasmines, their light tolerance is slightly lower. We often say "the undead jasmine", but no one says "the undead gardenia". That is to say, it likes light, but it can't be exposed to the sun in any case. Different breeding environments, different soil components, different sizes and thickness of flowerpots, don't underestimate these "differences", they are the key factors to determine whether gardenias can be exposed to the sun.
Different breeding environments
In our life, there are many flower friends who like to raise gardenias. Although it is a plant in the south, it is also loved by many flower friends in the north. It can be said that the number of gardenia lovers and raisers in the north is no less than that in the south. However, there are great climatic differences between the north and the south of our country. Take the weather in October now. Some cities in the north have already had snow, while gardenia lovers in the south are still wearing short sleeves. Therefore, in the north in summer, gardenias can promote normal growth by expose to the sun, while in the south, with the high temperature of 38 degrees Celsius or above, appropriate shading is really needed for them, otherwise, their leaves are easily sunburned.
The same pot of gardenias, if you put it on the muddy ground to expose to the sun and put it on the high-level platform to expose to the sun, the results are also very different. Gardenias on the ground are more "sun resistant"; while gardenias on high-level platforms are different. High temperature baking can easily cause dehydration or yellow leaves if they are not adapted to the outdoor environment.
Different soil composition
Some flower friends will ask, what does soil have to do with light? In fact, all aspects of plant growth are interlocked. Gardenias are plants that like slightly acidic soil. Generally, we recommend that they be given loose and breathable slightly acidic soil, which can quickly penetrate and be absorbed by the roots after watering. The roots grow well and strong, and can continuously supply nutrients to the branches and leaves, so the resistance is strong and the more they are exposed to the sun, the stronger they become. If you only use simple yellow soil for planting, it is easy to compact and not breathable after watering, the roots can not breathe smoothly, and it can not grow well. It can not provide nutrients to branches and leaves normally, so the resistance is poor and the leaves are easy to turn yellow when exposed to strong light.

Different sizes and thickness of flowerpots
Sometimes flower friends like to use plastic pots, with thin pot walls and small sizes. When encountering high temperature weather, the branches and leaves wither after exposure to the sun. Especially when the soil is damp, the evaporation of water increases, the temperature of the soil around the roots increases, and the roots are "roasted" inside, which is easy to rot. However, gardenias are also water-loving plants. Under strong sunlight, it is possible to "roast" the leaves without watering for a day, so it is necessary to shade them in time.
Using thick-walled and short fat ceramic pots or mud pots has good heat insulation, and the roots can be protected at any time, which is commonly known as "not seeing through the sun", so that the branches and leaves of the plant can grow strong.
Environmental changes affect light tolerance
If your gardenia grows well in a diffused light environment, but you suddenly move it to a strong light environment, it will have discomfort within a day, such as yellow leaves and burnt leaf edges. If gardenias lack light, first move them to a bright place, and then gradually increase the light intensity to make them slowly adapt to the surrounding environment to prevent various discomfort symptoms.
Conclusion
On the whole, gardenias are heliophilous plants. Their growth and flowering need sufficient light stimulation. As long as the breeding temperature is kept below 32 degrees, gardenias can be exposed to the sun. When the temperature is higher than 35 degrees, shading can be given at noon. In spring, autumn and winter, the light is not strong, and full sun can also be given. Therefore, expose gardenias to the sun and master the breeding methods flexibly according to the actual situation to minimize the damage to the plant.
